Louis, did you climb Mt Zeil? If so, I am very jealous!
I wanted to climb it back in 2004, on a bushwalking trip to central Australia (we did a few 3 day walks). But it was impossible at the time to get access to the pastoral lease just outside the park. We could have walked in from Redbank Gorge and back again, but my walking mates weren't keen on it (wish we did).
One of my aims one day is to do the whole eastern and western MacDonnel ranges, solo, unsupp, starting at the far east end. I dont think anyone has done that solo and unsuppported. I know Sir Warren Bonython, at least, has completed both the legs, although with partners and doubtless with some food drops (such was his style).
The MacDonnel ranges and Central Australia truly is a magnificent place, it is so ancient and timeless, and rugged. I will never forget those walks, especially Mt sonder, and the three day loop we did that included Mt Giles. Wow.
Now I have to organise going back there...
